Caroline Flint: I welcome my hon. Friend the Member for Wigan (Lisa Nandy) to the Front Bench and wish her all the best. I thank her for her kind words, as I thank other colleagues across the House for theirs.
	Of course competition should put downward pressure on prices. I have discovered, through a freedom of information request, that despite a tough letter from the Secretary of State demanding price cuts for energy companies in May because of low wholesale costs, responses have not been received from Centrica, RWE npower, E.ON and EDF. The Competition and Markets Authority interim report made it clear that 70% of customers on their suppliers’ standard variable tariff are being overcharged and it recommended a better deal. Will the Secretary of State therefore join me in calling for the introduction of a protected tariff—a default tariff, as it is known—to make the energy market more competitive and give a fair deal to the consumers who are being ripped off?
